Kensington K33926US Universal Notebook Docking Station with VGA/DVI and Ethernet Review Listen to this article


A lot of people are going to a laptop only computing experience.  There are even some that are going to a netbook only experience as a netbook is all they need.  Sometimes, however, it is nice to have a screen that is bigger than what a netbook can provide.  The same can be said about the touchpad and the keyboard.  Wouldn’t it be nice to plop your laptop or netbook down and have it attached to a 24 inch LCD?  That’s where this dock comes in.


The Kensington K33926US is essentially, at it’s core, a USB hub.  However, it also has many other devices attached to the hub internally that will help a user expand that laptop or netbook into a much more satisfying experience.

There are a total of 5 USB ports on this device for plugging in thumb drives or other USB devices like keyboards and mice.  The idea here is that you use these ports to attach a full sized keyboard and a mouse.  These ports also remain powered when your laptop is off so you can use it to charge your USB devices.


It doesn’t stop here.  There is also a Ethernet port on the back that you can attach to your router.  This let’s you use a reliable wire instead of a wifi connection that can be unreliable at times especially in areas where there are a lot of access points.  Besides, you are sitting down to do some significant work and not just surfing on the couch and the last thing you need is your connection dropping.

There is also a USB sound device built in to this universal dock.  This let’s you hook up a decent pair of speakers and let them sit at your desk while you are out and about.  This also avoids the possibly noisy integrated sound card that is in most laptops.  I’ve often found that USB sound devices sound much better than any integrated device and the sound built into the Kensington K33926US is pretty good.  If you don’t want to use the speakers, you can use the headphone jack on the front of the dock to keep your music to yourself.


Lastly, Kensington included a DisplayLink USB graphics card in the device.  You can attach a DVI or VGA monitor to this port.  To adjust which side the monitor is on, you can click the tray icon and do this or you can use the standard Windows display applet.  Using the icon is the most convenient.  XP remembers what you input into the applet so the next time you connect the monitor will be setup correctly.

The Linux Test

ThermoWorks Thermapen Mk4

It would not be one of my hardware reviews if I had not tried to use this with Linux.  The great news here is that almost everything works.  The USB ports, the sound and the Ethernet jack all work.  The only item that does not is the DisplayLink graphics.  DisplayLink is a relatively new technology and the good thing is that there is a open source driver that is close to implementation.  In fact, a version of it is in Ubuntu 9.10, but it is not the dynamic version that is truly needed to make this work for a laptop or netbook.  This could be added to the Ubuntu 10.4 or “Lucid Lynx” release, however this is slated to be a Long Term Support release.  There usually isn’t much new stuff added to a LTS release with it focusing on taking what the current release has and making it stable for long term support.  However, I could be wrong.  The good thing is that DisplayLink will be supported in the very near future in many distributions and if you are brave, you can compile the module and have support today.


Kensington and others have long made docks. Now there are docks that are as nearly as full functional as most proprietary docks that you buy from the likes of Dell or Lenovo.  The great thing is when you get home, you hook that one USB port up and you get a full sized keyboard, a mouse, wired Ethernet and a regular monitor and you only use one of the precious USB ports on your laptop.

The only downside to this dock is that you need to have a wall wart plugged in to use it and there is no way you can power your laptop over the same USB port.  You will have to plug a AC adapter into your laptop or run on batteries.

You don’t even have to use a CD to install the driver as it has a built in “CD Rom” that will autorun if you have autorun enabled.  If not, just run the autorun.exe on the CD image.   Once the driver is installed, the CD image is still there so you can always reinstall the driver but you can’t put a updated driver in this space.

This works on either Windows XP or Windows Vista.  To get one that works on the Mac, order model K33930 from Kensington.  The K33930 will not install the driver automatically and comes with a CD with the drivers for WinXP, Vista and Mac OS X.

The Kensington K33926US is available for $116.90 on Amazon.

Kensington sent me a sample of the K33826US and I thank them for letting me keep it.  If I get the Display Link module working on Linux, I will definitely post on it here.

What I liked: Worked as it should and is pretty useful.

What needs improvement: I wish it had worked with Linux, but it’s not far off.  In the mean time, I can still use it as a USB hub with a few extra features.  Also I am surprised that it would not work for me when I tested in Windows 7.  Yeah the box said it was XP and Vista only, but I have to try as others will.
